Journal ArticleDOI
Proteoglycan Depletion–Induced Changes in Transverse Relaxation Maps of Cartilage
TL;DR: T2-weighted imaging neither yields quantitative information about the changes in proteoglycan distribution in cartilage nor can be used for longitudinal studies to quantify proteogly can-induced changes.
Journal ArticleDOI
Sensitivity of MRI to proteoglycan depletion in cartilage: comparison of sodium and proton MRI.
Arijitt Borthakur,Erik M. Shapiro,Jennifer Beers,Sagar B. Kudchodkar,J B Kneeland,Ravinder Reddy +5 more
TL;DR: Results from these studies demonstrate that sodium MRI is both sensitive and specific in detecting small changes in PG concentration, whereas proton density and relaxation properties are not sensitive to small changes to proteoglycan content.
Journal ArticleDOI
CEST signal at 2ppm (CEST@2ppm) from Z-spectral fitting correlates with creatine distribution in brain tumor.
Kejia Cai,Anup Singh,Anup Singh,Harish Poptani,Weiguo Li,Weiguo Li,Shaolin Yang,Yang Lu,Hari Hariharan,Xiaohong Joe Zhou,Ravinder Reddy +10 more
TL;DR: The Z‐spectrum acquired at low saturation RF amplitude was modeled as the summation of five Lorentzian functions that correspond to NOE, MT effect, bulk water, amide proton transfer (APT) effect and a CEST peak located at +2 ppm, called CEST@2ppm.
Journal ArticleDOI
Reduced plasma antioxidants in first-episode patients with schizophrenia.
TL;DR: The present data suggest that a defect in the antioxidant defense system (AODS), which may lead to oxidative damage, occurs early in the course of illness and is independent of treatment effects.
Journal ArticleDOI
Proteoglycan loss in human knee cartilage: quantitation with sodium MR imaging--feasibility study.
Andrew J. Wheaton,Arijitt Borthakur,Erik M. Shapiro,Ravinder R. Regatte,Sarma V.S. Akella,J. Bruce Kneeland,Ravinder Reddy +6 more
TL;DR: The data suggest that sodium MR imaging has potential for use as a quantitative diagnostic tool to measure changes in proteoglycan content in early-stage osteoarthritis.
